Description

Produce textile product method, being capable of thus obtained product and the recycling product Method

The present invention relates to make in the application of such as floor covering (for example, carpet, carpet tile, scatter rug and cushion) Textile product, their manufacture and the method for recycling these products.

For covering the textile product (for example, as carpet) on floor usually by stitching yarn on the first material with shape At the yarn bearing bed with the yarn cluster stretched out from upper surface.Usually carried with the latex impregnation yarn of crosslinkable polymer Layer.Emulsion polymer immerses after product, and latex is crosslinked so that yarn cluster (yarn tuft) is permanently anchored on suitable position It sets.Basal layer (also referred to as substrate backing is commonly known as before the combination of yarn, the first material and latex in the art And/or substrate pads).In order to improve the engineering properties such as dimensional stability of generated textile product, carrier material has been used The second layer (in the art before also referred to as the second layer and/or support plate), be usually glued at the back side of basal layer To form the stacking textile product with desirable properties.

Hot-melt adhesive (HMA) has been used for bonding the basal layer and the second layer in roll carpet, because HMA is relatively just Preferably and it is easily obtained.

In general, basal layer, the second layer and connecting their adhesive and respectively containing with different engineering properties far apart Different material, because they are designed to execute different functions.

Prepared using crosslinkable latex basal layer have the shortcomings that it is a variety of such as some or complete in those described below Portion.

If emulsion polymer be it is water base, textile product can have low waterproofness and moisture can permeate the production Product.The risk that this improves the mildew that product can be made to degrade and mould is formed.In addition, being typically found in latex composition Residual monomer trace can also reduce air quality, this is environmental hazard.Therefore, when latex base floor covering is exposed to high humility When, such as when being used in hall or washroom, it may be necessary to it is replaced as frequently as floor covering.

Alternatively, surface is living if latex is the hydrophobic polymer for example, by using surfactant-dispersed in water The presence of property agent can also improve product to the sensibility of moisture.Some latexes may include styrene (for example, as styrene fourth Diene rubber (SBR)), this can lead to the residual styrene of a large amount in the product.Environment and it is other due to, preferably The amount of volatile organic compounds (VOC) is low as much as possible in textile product.

Because latex base textile product is used for the component in basal layer and the second layer using dissimilar material, if to return These components are received and re-used, then need to separate each of which.However, yarn and the first material are wrapped securely It is embedded in (for example, vulcanization) emulsion binder of chemical crosslinking.Therefore, in latex base textile product, each group of basal layer Divide and is not easy to be separated.Although having developed some recovery technologies come some in solving these problems, such method is very high It is expensive and do not allow to recycle all material used completely.Therefore, recycling latex base weaving floor covering is unpractiaca, they It is discarded, burns or shreds.The floor covering of chopping is processed usually in landfill, due to the cream of crosslinking Glue cannot be by largely biodegrade, so many years will be present in the residue of chopping.

Some in order to solve these problems, the polymer such as polyolefin and polyurethane for having developed a variety of synthesis come Instead of the emulsion polymer in textile product.Such replacement is sufficiently satisfactory.

That attempts in these and other prior art carpet for solving the above problems some is described in following file.

EP747525 (BASF) describes recyclable carpet, is prepared by following substance: the backing comprising prominent cluster is (excellent Selection of land, prominent cluster are identical as the material of backing) and be integrated to using hot-melt adhesive (HMA) substrate backing back heat Plastic substrate carrier.Backing and cluster are made of such as material of nylon, polyolefin and/or polyester, and thermoplastic carrier is by for example gathering The material of alkene, ethylene vinyl acetate (EVA) and/or polyvinyl chloride (PVC) is made.HMA is applied to the back of substrate backing Face is to be locked in suitable position for nanocluster and serve as the cushion between backing and carrier, therefore it is selected as and backing The polymer of polymer and carrier is compatible.Preferred HMA is caprolactam base copolyamide, but compatible polyene also can be used Hydrocarbon and/or copolyester adhesive.It can be by recycling carpet as follows: being heated to being enough softening HMA (again) but lower than tufted The temperature of the fusing point of the polymer of backing and carrier substrate, therefore carpet is separated into its two group stratification.

US3975224 (Lutravil Spinnvlies) discloses the method for manufacture nonwoven web, and the net is used as being used for The enhancing of the dimensionally stable of tailor's cushion type tufted carpet and back lining materials.The net has minimum 200p/g/m²Opposite seize drawing Stretch intensity, the extension at break not higher than 50% and the contraction that 1% is not higher than at 160 DEG C.Nonwoven web include multirow matrix filament and The pencil of parallel lines of binder filament.Matrix filament contains the preferred polyethylene terephthalate of polyester of fusible weaving.Bonding Agent filament contains the polymer of such fusible weaving, and the fusing point of the polymer is higher than 160 DEG C and melting than matrix filament Point is 30 DEG C low.Suitable binder polymer is as described below: polyamide or copolyamide are (for example, polycaprolactam or gather oneself The copolymer of lactams and polyhexamethylene adipamide)；Polyester or copolymer are (for example, polyethylene terephthalate/poly- isophthalic two Formic acid second diester, polyethylene terephthalate/adipic acid second diester or terephthalic acid (TPA), M-phthalic acid, ethylene glycol and The quarternary copolymerized ester of Isosorbide-5-Nitrae-hexamethylene diethanol)；Isotactic polyolefin (for example, isotactic polypropylene) and the poly- ammonia of line style Ester.

US5240530 (Tennessee Valley Performance Products) describes recyclable carpet, With the substrate backing comprising synthetic fibers cluster outstanding, the synthetic fibers cluster is heated so as to substrate backing and by for example complete With the second backing of extrusion board fusion made of vertical structure polyolefin.Substrate backing and the second backing and fiber may include thermoplasticity Plastics.The bibliography directly instructs reader: conventional emulsion binder or hot-melt adhesive are not used, because both It is recited as " carpet is prevented to be recovered " (the 4th column, 16-17 row).

US5538776 (Hoechst Celenese) (=EP0604897) describes recyclable thermoplasticity tufted carpet, It is made by the substrate backing with cluster and using the second backing that polyester hot melting adhesive phase is adhered to substrate backing.HMA Instead of emulsion binder (referring to the 2nd column, 50-51 row) and nanocluster, substrate backing, HMA and the second backing are by a type The thermoplastic (preferably polyester) of type is made.Therefore, it can be returned by known method, such as by glycolysis or Methanol Decomposition The method of pinching ester, Lai Huishou carpet.However, these carpets will be without good engineering properties, because cluster will not be firm enough Admittedly be anchored on carpet, this is because HMA itself will cannot provide bonding good enough when lacking emulsion binder.

US2010-0112250 (Eastman Chemical) describes the hot-melt adhesive (HMA) prepared by polyester, The polyester includes the diol component as Isosorbide-5-Nitrae-hexamethylene-dicarboxylic acids of diacid component and comprising at least two glycol, described Glycol is selected from 1,4-CHDM, triethylene glycol and diethylene glycol.These HMA are described as being suitble to be coated on label, Such as it is described for the seam adhesive of roller application label.These polyester are not provided in this document will be suitable for preparation spinning Knit the suggestion of product such as carpet.

US2010/0260966 (Beaulieu Group) discloses the carpet tile of dimensionally stable, contains incorporation stabilizer Nonwoven course (cushion material).Stabilized course is set to be adhered to face using polymeric binder layer Fabric (face fabric).The example of suitable polymer adhesive is as set forth below: PVC, polyethylene, modified polypropene, Ethylene vinyl acetate, modified PET and its blend.In one embodiment, it for example squeezed, heated by suitable method Change or stabilized course, face fabric and adhesive phase are forced together by tape lamination.However, no matter which kind of adherency side used Both method, in order to ensure well-bonded between course and face fabric, polymer adhesive must largely permeate. This make recycle carpet tile it is very challenging because its constitute polymer material it is incompatible, cannot be recycled together and Still it is difficult to separate.

US2011/039056 (Interface International) discloses the carpet comprising following adhesives, described Adhesive can lose its adhesive function and being handled with the solvent of heating, and (such adhesive is referred to as " convertible hot water Property solvent cement ").Preferably, transformable adhesives are the esterification expanded starch of plasticizing.Utilize such transformable adhesives Production carpet allows adhesive loss of function and each carpet components is allowed to separate for better simply recycling.However, in this way Adhesive may not especially securely, if starch base may provide low moisture resistance to water sensitive.

W02007/127222 (Mohawk Industries) describes hot-melt adhesive (HMA) and is used to prepare stacking ground The purposes of blanket block.Carpet tile includes the tackifying resin of tufted veil electric, substrate backing, HMA pre-coating layer and at least 20 weight % With at least two solvent-free layer.Preferred pre-coating layer contains the polyethylene of 2-80 weight % and the tackifier of 20-98 weight %. These stacking blocks have complicated multilayered structure, this makes their production costly.It is firm between these layers in order to realize Bonding, need hot-melt adhesive fully to penetrate into other materials, therefore be difficult by each component part separate and these blocks not It can easily be recycled.

EP1598476 (Klieverik Heli) describes method of the production as the backing of the intermediary of manufacture carpet, Wherein fiber (yarn) is anchored on appropriate position without using latex by the backing.Backing includes such plate, has and passes through Wear the thermoplastic fibre villus (piles) that upper surface that the thickness of the plate is sewn and from plate is stretched out.It is supplied along heating roll surface The bottom surface of backing is squeezed to (fiber is upward) backing and towards roller, therefore fiber will melt.Klieverik is pointed out: after cooling, Fiber is firmly anchored each other and is anchored with backing without emulsion polymer.A kind of introduction of embodiment: can extraly by Powdered thermoplastic adhesives (for example, hot-melt adhesive) are coated to the bottom surface of backing, therefore the surface heated is by fiber And adhesive melts between villus, adhesive and backing together to generate good adhesiveness.In another embodiment In, after heating, pressure can be applied (for example, logical to backing and villus on the direction (that is, from below) perpendicular to backing surface Excess pressure roller) the fiber of plasticizing is smeared (smear) to together to enhance their mutual bonding, therefore allow to heat Roller is maintained at will be under the lower temperature that be melted and individually heating lower than fiber.This method provides the advantage that intermediate back Lining can be recycled easily, because fiber and backer board can be made of identical polymer.There is no penetrate into fibre fluff not Capacitive latex (referring to [003] section).Compared with method in the prior art, energy and cost of material are also saved.However, should Method still has the shortcomings that.For applying many (for example, wherein fiber is subjected to high mechanical load (for example, in automobile, fire The inside in vehicle, aircraft, office, shop etc.)) in use, fiber is still not enough firmly anchored on backing.Therefore, by In the practice of intermediate backing manufacture carpet described in Klieverik, it is still desirable to coat additionally (incompatible to the bottom surface of backing ) adhesive or latex and/or to penetrate into HMA extensively in carpet pile and backing enough viscous to be provided using individual HMA With joint efforts.Such incompatibility material and/or the presence for being embedded in HMA will mean that such carpet is difficult to recycle.

WO 2012/076348 (Niaga) describes the method for manufacture textile product, and the method improves the anchor of yarn Tenacity.In this approach, when squeezing the first yarn loading plate against heating surface, the relative velocity of adjustable plate and surface To provide the additional machinery power in machine direction (see below) between them, which spread thread material, simultaneously Thread material still melts, to generate stronger bonding between the first plate and yarn.Although in theory, in many In the case of, the second additional support plate may be no longer necessary, but this document is instructed: such support plate may be still useful, when It includes dependent on the thermal reversion reaction being present between the reactive molecule on the interface between textile product and carrier material Reactive adhesive when, it is especially true.It is usually obtained with by other type adhesives such as hot-melt adhesive (HMA) Bonding is compared, and such reactive adhesive provides much better than bonding.However, although the use of reactive adhesive provides heavily fortified point Solid bonding and can be recovered (unlike latex), but it is using still resulting in the textile product without optimal mechanical property.Make Had another disadvantage that with chemical reactivity adhesive: the two kinds of components and adhesive to be connected must carry co- reactive group. Therefore, the polymer for being used to prepare substrate backing and/or cluster may need the chemical modification in additional step, because standard Commercial polymer can not contain the required functional group for being suitble to be used together with reactive adhesive.

WO2000-61853 (Polyloom Corp.) describes such carpet, and wherein the bottom surface of substrate backing is heated The single fiber of the part yarn back ring (back loop) integrally to be fused together to form carpet basis (also referred to as Fabric (greige goods)), then coating on it has the thermoplastic polyolefin of recurrent polar segment (polarity TPP) Hydrocarbon polymer coating.Polarity TPP coating makes essentially all of fiber adherency or whole fusion in back ring.One of polarity TPP Example is maleic anhydride modified polypropylene.The method that yarn cluster is connected described in Polyloom is different from method of the invention. Polyloom is not instructed or is recognized: when fusing so that the back side flattens and improves the adhesiveness of coating thereon when, on MD to The advantages of yarn applied force.Therefore, the fabric of Polyloom still has uneven coarse and uneven comprising yarn ring and section Smooth bottom surface, the bottom surface will cannot obtain fabulous bonding with any coating thereon coated.Therefore, with the present invention on the contrary, must The polarity TPP coating of strong bonding must be used.TPP is far different with HMA.This document largely describes (in the row of page 9 the 3rd to The row of page 11 the 9th) using some so-called problems of hotmelt adhesive (HMA), this includes: extremely low compared with olefin copolymer Tensile strength；When with cooling down after coating carpet, their viscosity is improved.Therefore, the reader of this document should not by strong introduction Carpet is prepared using any HMA, needless to say HMA is used to adhere to back sheet on the base layer as individual adhesive To form carpet.

US5876827 (Polyloom) is described similar to carpet described in WO2000-61853, and it includes to be similar to Polypropylene yarn is hot-melted onto polypropylene substrate backing by mode described in WO2000-61853.This document, which also illustrates, to be made So-called disadvantage (referring to the 2nd column 42-65 row) and specifically recite that " hot-melt adhesive carpet ... is not easy to when with HMA It is recyclable " (the 2nd column 57-59 row), this directly teaches will be far from carpet of the invention.

WO2012-060698 (Interface) describes the method for manufacture carpet tile, wherein cluster yarn heat is fused to Simultaneously enhancing nonwoven material layer is added to improve the dimensional stability of carpet tile in support material.This application set forth with latex, bonding There are disadvantages (referring to page 1,19-28 row) therefore it is taught that far from carpet of the invention for agent or HMA pre-coating nanocluster.

FR2565610 (SIRS) describes such carpet, wherein between tufted nitride layer and support plate have vinyl or The resinous coat of olefin polymer or copolymer.Preferred resin is polyethylene, polypropylene and ethylene vinyl acetate copolymer. There is no suggestion that these polymer can be hot-melt adhesive, and in fact resin is described as with powder or film and athermal solution Form is coated.

EP2172589 describes the straw mattress of synthesis, is prepared by blade-like (bladelike) element of elastomer latex support And it is used to form the artificial turf for sports ground.EP1705292 also illustrates chinampa, wherein the lawn be pass through by To support surface come what is prepared, the support surface is optionally adhered on carrier fiber heat fusing.All do not have in this two parts of files There is hint: HMA can be used to adhere to carrier layer.In view of the high abrasion that this artificial playing surface is born, those skilled in the art Member, which will avoid passing through, mixes HMA in support plate to improve any of these green surfaces.

Therefore, it can be seen that: the method for current manufacture textile product and the product manufactured by them are with a variety of Disadvantage described in text.For example, current manufacturing method generates such textile product, it is not easy to be resistant to very high mechanical negative It carries, the risk of product is pulled with yarn during the use improved；Engineering properties with unoptimizable and/or it is difficult to return completely It receives.Preferably, it would be desirable to possess the recyclable textile product for having optimal mechanical property, wherein yarn secure anchorage is wherein.

It can also be seen that hot-melt adhesive (HMA) have the shortcomings that when being considered in for carpet it is specific.Lower than it Setting temperature when, HMA is usually frangible and tend to tear under mechanical shock or rupture, and so as to cause first, (yarn is held Carrying) material separates with carrier material.Different materials in textile it is different to the reaction of its environment (for example, be exposed to heat or When moisture, differently expand), this can also cause further stress in HMA, so as to cause carrier material separation.Therefore, people Think, in order to make HMA provide sufficient bonding, they must be sufficiently submerged in textile material to overcome this problem and offer Good nanocluster bonding force.Such impregnated structures are difficult to recycle, because their constituent component is difficult to separate.Therefore, still Substitute of the HMA as adhesive in weaving floor is not widely used, because if being easy recycling, then the product generated is considered It is not very durable；If durable enough, it is difficult to recycle.

Therefore, unexpectedly, such hot-melt adhesive can be used to prepare textile product, the hot melt adhesive Agent provides sufficiently tight and lasting anchoring for the yarn under high load and also product is easily recycled.

It is not desired to be not to be considered in any way limitative of the present invention by as described herein any theoretical or supposition constraint Range, for using the effect observed of the present invention, some possible explanations have been provided below in applicant.

In view of the usually frangible attribute of hot-melt adhesive, have previously been thought that: hot-melt adhesive is used alone will not Generate good engineering properties.Unexpectedly, applicants discovered that the substrate backing that ought be wherein sewed with yarn is subjected to fiber knot When conjunction process (such as described in WO 2012/076348), it is very firm and mechanical lasting to generate that hot-melt adhesive can be used Bonding substrate plate and carrier board to be linked together.Even more unexpectedly, applicants discovered that with reactivity is utilized Adhesive (the preferred adhesive of WO 2012/076348) is compared, and yarn is shown even more strongly in conjunction with substrate backing. This is unexpected, because having previously been thought that: compared with the reactive adhesive bonded using covalent bond, hot melt adhesive Agent generally generates relatively weak combination (based on Van der Waals force or Hydrogenbond).

Applicant thinks: hot-melt adhesive especially those described herein HMA (and optionally, stable carrier board) Presence can independently improve the mechanical stability of textile product of the invention and avoid the need for adhesive latex therefore to assign Good mechanical stability and also fully it is anchored yarn.Therefore, because any emulsion binder is not utilized, so of the invention Textile product is easier to be divided into constituent component and can be easy to recycle.

The improved mechanical resistant impact of hot-melt adhesive (the frangible category of its hot-melt adhesive for being not subject to solidification Property) can also be related with the size of adhesive phase, such as when described adhesive layer is applied to through heat and pressure treatment (calendering ) substrate surface on when, can be coated by more unfertile land.Thin layer obviously can be more flexible and can be by the problem related to brittleness It minimize.However, this explanation may be incorrect and the precise reason why of effect observed it is on the knees of the gods.

Unexpectedly, in textile product of the invention, HMA shows more preferably than reactive adhesive.Applicant is not Wish to provide the theoretical constraint of stronger combination than reactive adhesive by any hot-melt adhesive why in the present invention. But a reason may be: HMA more easily permeates than reactive adhesive and impregnates fiber and HMA is not needed in molecular water Base pad material is closely contacted on flat, and this is that the coreaction component formation covalent bond institute of reactive glue is required 's.Fiber combination method described in WO 2012/076348 is considered generating the surface being completely smooth, unexpected about HMA Performance the observation that may be attributed to applicant is explained in more detail: in fact, this method is still in the rear table of back lining materials Intrinsic discontinuity is left on face.If this hypothesis is correctly, when yarn is applied to discontinuity zone (its Can usually be indicated by cluster yarn road (lane)) in when, as yarn melts, can be produced between thread material and rear surface Raw SPA sudden phase anomalies (this may also interpret the zebra stripes pattern being commonly seen), this will be enlarged by the distance between coreactivity material simultaneously Prevent their reaction.When textile product is in mechanical load (especially if textile deforms), this SPA sudden phase anomalies Mechanical tension also can be improved in boundary.If hot-melt adhesive is applied in rear surface, it is believed that: compared to other bondings Agent type is (for example, reactive adhesive, for which, direct contact on a molecular scale are to make chemical reaction generation must Need), this can preferably permeate these SPA sudden phase anomalies regions.Therefore, the use of HMA can spread mechanical force simultaneously in large area The localised tension being subjected in these regions is reduced, then to assign improveds mechanical resistant loading (that is, forming heavily fortified point by this interpretable HMA Solid combination).

The present invention is illustrated by following non-limiting figure, in which:

Fig. 1 is shown across the cross section of expendable latex Carpets in the prior art.

Fig. 2 shows the cross section in the prior art with the recyclable carpet of nanocluster anchoring of difference.

Fig. 3 shows the cross section of the stacking carpet in one embodiment of the present invention.

Fig. 4 shows the cross section of the non-laminated carpet in another embodiment of the invention.

Fig. 5 schematically illustrates matching for the method application fiber combination method according to WO 2012/076348 It sets.

Fig. 6, which schematically illustrates for the second plate (being the polyester sheet of dimensionally stable in this case) to be applied to, utilizes figure The configuration at the back side of 100% polyester product of the production of method described in 5.

Typical expendable latex Carpets in the prior art are shown in Fig. 1.Carpet (1) has by such as gathering Substrate backing (3) made of the material of propylene (PP).There are hole (5) in substrate backing, nanocluster (7) is in the hole and from preceding table Face (9) is stretched out.Nanocluster is glued on substrate backing by the emulsion binder (11) being crosslinked to form tufted pad (13).Benefit The second supporting carrier (15) made of the material such as PVC or PET is glued at tufted pad with additional bonds oxidant layer (19) Back side (17), the additional adhesives can be emulsion binder or can also be Solid thermoplastic's glue.

Since emulsion binder (11,19) penetrates through carpet (1), so nanocluster (7) is securely held in pad (13) On, but this is but also carpet can not be recovered, because incompatible latex (11,19) cannot backing, nanocluster with carpet It is separated with carrier component (3,7,15).

The recyclable carpet in the prior art manufactured using hot-melt adhesive (HMA) is shown in Fig. 2.Carpet (101) there is the substrate backing (103) made of HMA compatibility material such as polyester (PE).Also there is hole in substrate backing (105), nanocluster (107) through hole outstanding is embedded in front surface (109).Nanocluster passes through HMA (111) such as polyester hot melting Glue is glued on substrate backing to form tufted pad (113).It will be by thermoplastic material such as polyester system using HMA layers (119) At the second supporting carrier (115) be glued at the back side (117) of tufted pad.

Backing, nanocluster and carrier component (103,107,115) are made of compatible thermoplastic material such as polyester, because This carpet can be recovered.However, the infiltration poor due to HMA adhesive (111,119), so nanocluster (107) is faintly solid It is scheduled on pad (103), to form fragile faint combination.

Recyclable stacking carpet of the invention is shown in Fig. 3.Carpet (201) has by material such as polyamide or gathers Substrate backing (203) made of ester.There are hole (205) in substrate backing, nanocluster (207) is in the hole and from front surface (209) it stretches out.Nanocluster (207) is made of the material such as PA or PET compatible with substrate backing (203).Nanocluster (207) is logical Fiber combination method (that is, as described in WO 2012/076348, melting yarn) is crossed to be adhered on substrate backing (203), with Tufted pad (213) are formed as base pad without the use of any adhesive.It will be by using HMA such as polyester hot-melt adhesive (219) Second supporting carrier (215) made of material such as PET is glued at the back side (217) of tufted pad.

In this embodiment, since substrate backing, nanocluster and the second backing component (203,207,215) are by phase The thermoplastic material of appearance such as polyester is made, therefore complete carpet (201) can be recovered.Since fiber combination method is (by yarn Be melted on backing) and single layer HMA (219) be applied in combination, nanocluster (207) and pad (203) firm connection.It should realize It arrives: although in this embodiment, material is compatible, this is because we are replaced using complete-polyester carpet in similar It (is not shown in Fig. 2 in property embodiment, but there are similar structures), it can be for example comprising incompatible material such as polyamide cluster Shape object (for example, nylon 6) and polyamide substrate backing (for example, nylon 6) and the second backing of polyester base (for example, PET).Polyester It is compatible that (and generally will not be) not be needed with polyamide portion.In this embodiment, if HMA is reversible (for example, logical Cross heating), then nylon yarn and the first plate of nylon can be detached from PET support layer, so that nylon and the part PET can be independent Recycling.

Recyclable non-laminated carpet of the invention is shown in Fig. 4.Carpet (301) have by material such as polyamide or Substrate backing (303) made of polyester.There are hole (305) in substrate backing, nanocluster (307) is in the hole and from front surface (309) it stretches out.Nanocluster (307) is made of the material such as PA or PET compatible with substrate backing (303).Therefore, this implementation In mode, when nanocluster is polyamide, substrate backing is also polyamide-based；When nanocluster is polyester nanocluster, substrate Backing is polyester base.Nanocluster (307) (that is, as described in WO 3012/076348, melts yarn by fiber combination method Line) it is adhered on substrate backing (303) and substrate backing is additionally glued at by HMA (311) such as polyester hot-melt adhesive On, to form the non-laminated tufted carpet (301) of complete single layer.

In this embodiment, when substrate backing and nanocluster component (303,307) are by compatible thermoplastic polyester When being made, complete carpet (301) can be recovered.Due to fiber combination method (yarn is melted on backing) and polyester HMA (311) be applied in combination, nanocluster (307) and carpet (301) are firmly combined, and carpet is formed by single back sheet (303).? In this embodiment, other carrier or support layer is not needed to provide dimensional stability for non-laminated carpet (301).However In the embodiment that nanocluster and basal layer are polyamide (for example, nylon 6), it is (excellent to be usually also additionally required the second backing Selection of land, PET) assign the dimensional stability of final textile product abundance.

Fig. 5 schematically shows the configuration of the method application fiber combination method according to WO 2012/076348. In configuration shown in fig. 5, there are the first heat blocks 500 and the second heat block 501, it is therefore an objective to heat heater element, generate heat Element is also respectively expressed as fever blade 505 and 506.These heater elements are respectively provided with working surface 515 and 516, described Surface is contacted with product to be processed, and the product is usually to pass through sewing process to the substrate carrier for applying yarn thereon. Both working surfaces all have the working width of 18mm, and intermediate distance (immediate distance) is 26mm.Product Rear surface contacted with the working surface of heater element.In order to apply pressure appropriate to product to be processed, exist Teflon support 520 be used to offset the thrust being applied on heater element.In operation, heater element is in instruction It is moved on the X of direction relative to product.In general, heater element be it is static, product is forced to support in working surface and Teflon It is passed up between object with the contrary side indicated with X.

In one embodiment, the product of above-mentioned configuration processing to be utilized is by can be with trade markE6412 It is commercially available from the substrate carrier composition of Freudenberg (Germany), the substrate carrier is 100% that melting temperature is about 280 DEG C Polyester backing, the cut pile with 100% PE yarn, fasciation areBacking.The melting temperature of yarn is about 285 ℃.The product is processed using the first heating element that temperature is 220 DEG C, with pre-add hot product.Second heating element is kept 298 DEG C at a temperature of.In order to keep the temperature at required level, heating block and heater element have insulation material layer respectively 510,511,512 and 513.Product, and the pressure applied using heater element are supplied with 12mm/ seconds (0.72 m/min) speed It is about 1.35 newton/square centimeter.This generates the rear surface with calendering (that is, in stitching yarns from the position that rear surface is stretched out Smooth) product.

Fig. 6, which schematically illustrates for the second plate (being the polyester sheet of dimensionally stable in this case) to be applied to, utilizes figure The configuration at the back side of 100% polyester product of the production of method described in 5.In the figure, the first roller 600 is depicted, is twined on the roller Around 2 meters wide netted described (prefabricated) polyester product.Product is unclamped from roller 600 so that its back side 217 and the second roller 601 contacts.The roller is provided with by the coating of hot melt adhesive layer 219 overleaf 217.For this purpose, a large amount of HMA219 are present in roller 601 And it between 602 and is heated.The thickness of this layer can be adjusted by adjusting the gap between the two rollers.HMA coats site Downstream is Second support plate 215, which unclamps from roller 603.The plate is squeezed and in unit 700 towards the tacky adhesion of heat It is cooling.The unit is made of two belts 701 and 702, and the belt is on the one hand towards substrate product stripper plate 215, another party Adhesive is cooled to lower than its setting temperature by face.Generated final products 201 are subsequently wound up on roller 604.Alternative In embodiment, laminating method and about fiber combination method described in Fig. 5 it is orderly (in line) occur.In this feelings Under condition, fiber coupling apparatus as shown in Figure 5 can be placed between roller 600 and roller 601.

In one embodiment, the HMA of coating is the polyester implementation for being used to prepare the carpet of embodiment 6 as described herein Example D.On the position that HMA is coated to the substrate backing back side, the suitable temperature of roller 601 is 140 DEG C.By making gap 2mm, Winding speed is 2m/ points, and roller 602 does not rotate and the peripheral speed of roller 601 is ± 1.6m/ points, and HMA will be with about 500g/m²Thickness Degree is coated.This is suitble to for polyester layer 215 being glued on substrate backing.

In another embodiment, wherein yarn pass through substrate backing stretch out (therefore, not only front extend, but also Across the back side, such as ring, fabric etc.), the yarn at at least partly stretching back side is melted.In this embodiment, until The yarn (typically, being almost parallel to the few fibers of back side operation) that small part stretches out the substrate backing back side is melted.? It was found that: when yarn stretches out the back side, they are easier to be melted and calendering is also simpler process, because melted material is practical It is upper be located at the back side " on ".Another advantage is: if desired, can be selected as its melting temperature remote for substrate back lining materials itself Higher than the material of the melting temperature of yarn, so that backing itself keeps not influenced by fusion process completely.This also offers Following advantages: the more substrate backing of dimensionally stable can be used at a temperature of the high process combined for fiber.

In another embodiment, wherein being coated in intermediary (or fiber adhesive pad) by the adhesive that will be melted Adhesive is provided on calendering surface, when coating adhesive, the temperature on the calendering surface of intermediary is higher than hot-melt adhesive Melting temperature.It has been found that: when coating adhesive, when the temperature on the calendering surface of fiber adhesive pad is higher than hot-melt adhesive When melting temperature, the product loading with the mechanical resistant even improved can get.It is believed that the temperature due to the back side is higher than The melting temperature of hot-melt adhesive, so this adhesive can penetrate into, such as on a molecular scale, the material (yarn of intermediate The material of wire material and/or substrate backing itself) to provide even stronger result.Particularly, when the second intermediary includes tool When having the material of low surface tension (and therefore having the tropism for repelling material such as adhesive), this can still be mentioned anyway For very lasting bonding.

Hot-melt adhesive is optionally provided thickness lower than 1mm, usefully lower than 0.5mm, more usefully 0.2- The layer of 0.4mm.But in the market in prior art carpet, the thickness of hot-melt adhesive is typically much higher than 1mm, applies for human hair It is existing: when the thickness of this layer is reduced to 1mm or lower, still to be able to obtain bonding appropriate.Accordingly, there exist in of the invention The preferred average thickness of adhesive phase in textile product (for example, between base thread bearing bed and carrier substrate) is 50 μ M-1mm, more preferably 0.1mm-0.8mm, most preferably 0.2mm-0.4mm.

The amount for being used to form the HMA of the adhesive phase in textile product of the invention (uses those skilled in the art crowd institute Known any suitable conventional method measures) it may is that the adhesive phase 0.01-1000g/m of unit area²HMA.Another In a kind of embodiment, HMA can be with 0.05-800g/m²Amount be coated.In another embodiment, HMA can be with 0.1-600g/m²Amount be coated.

In the present invention, in order to obtain the substantially complete recuperability of textile product, it is preferable that the first yarn carries material Material (substrate backing) and the yarn adhered to it have comparable fusing point.Usefully, yarn loading material and yarn come from Same material, such as polyamide (such as polyamide -6) or polyester.However, if these materials are different, advantageously, yarn The melting temperature of loading material is higher than the melting temperature of yarn.

As used herein, unless otherwise noted, " comparable fusing point " indicate: mutual fusing point 10 DEG C it It is interior, it is most preferably substantially the same more preferably within 5 DEG C.

Optionally (but in order to which obtain textile product essence or complete recuperability is non-required), any optional Carrier material (the second backing) is made of identical material type and also has can be with the first yarn loading material and yarn Compare (it is preferably substantially the same with the first yarn loading material and yarn, more preferably with the first yarn loading material and yarn It is identical) fusing point.If fusing point may compare and if yarn loading material (substrate backing), yarn and carrier material (the second back Lining) [and optionally even HMA] be made of identical material type, then and they optionally all pass through identical method quilt It recycles and can be not required to be separated together.Yarn loading material, yarn and carrier material may be the same or different.If carrier material is not Be same as yarn loading material and/or yarn, then preferably, the fusing point of carrier material than in yarn loading material and yarn at least A kind of, more preferably the two fusing point is higher.A kind of preferred carrier material is polyethylene terephthalate (PET).

However, carrier material with yarn loading material (and yarn) there is compatible fusing point to be not required.For example, if Carrier and yarn loading material are made of different polymer materials, then they can have different fusing points.Carrier and yarn Loading material can be easy to be separated from each other by heating reversible hot-melt adhesive, it is preferred that as described herein, The fusing point of HMA is lower than the fusing point of all other component, and is once separated, and if necessary, these materials can pass through difference Method is recovered.

In a kind of particularly preferably embodiments of the present invention, wherein yarn, yarn loading material and carrier are (if deposited ) be polyester, each self-compatibility of their fusing point, it is more preferably identical (as example will be the identical polymer of each freedom for example The case where when polyester formation).Preferably, in this embodiment, HMA, which has, is lower than yarn, yarn loading material and carrier Fusing point.It is highly preferred that in this embodiment, HMA may include similar with yarn, yarn loading material and/or carrier Polymer type (for example, polyester).

Hot-melt adhesive used in the present invention (it is optionally polyester) preferably have lower than yarn loading material, The softening temperature of the minimum melting temperature of yarn and carrier material (if present).

It will provide in the description about component (such as the yarn, the first (base for constituting textile product of the invention later Bottom backing) plate, adhesive and/or the second backing) substance preference.For example, the hot-melt adhesive suitable for the present invention It can be the HMA of the polymer comprising being represented as polymer P (as further limited later).Similarly, it is suitble to yarn, first (yarn carrying) plate, and/or the polymer of second (carrier) plate (if present) can be each independently comprising one or more next From the polymer for being represented as those of polymer R (as further limited later).In one embodiment of the invention, gather Close object P (main component of HMA) can with it is essentially identical for those of polymer R polymer, but preferably, HMA is than weaving It is melted at the lower temperature of other components of product, if polymer P is identical with polymer R, the more eutectic of HMA can be achieved Change, because HMA includes the other ingredients (that is, HMA is not necessarily pure polymer P) that can reduce melting temperature.

In another embodiment of textile product of the invention, substrate backing, the second backing or carrier board and hot melt Adhesive substantially contains identical polymer type, such as polyester.This greatly improves weaving when easily recycling abrasion The ability of product (textile product also referred to as worn).Entire abraded product can be melted in a single step simply to generate The melt of a type of conventional polymer.With the melting of the mixture comprising two kinds of polymer type such as polyamide and polyester Material is compared, much easier using this melted material in new opplication.Preferably, in this embodiment, HMA has Lower than yarn, the fusing point of yarn loading material and carrier.
